Abstract: EP--65229 A Benzazepine derivs. of formula (I) and their addition salts are new: (A is CH2CH2, CH:CH, NHCO, CH2CO or CR7:N (NH, CH2 or CR7 being at 5 position), and B is then methylene or carbonyl, or A is COCO and B is then methylene. E is ethylene, n-propylene, or n-butylene, opt. substd. by a 1-3C alkyl or is 2-hydroxy substd. n-propylene or 2- or 3-hydroxy substd. n-butylene G is methylene or ethylene opt. substd. by a 1-3C alkyl. R1 and R2 are hydroxy, 1-3C alkyl or alkoxy, phenyl (1-3C)alkoxy, one of them can also be H, or R1 and R2 are together 1-2C alkylenedioxy. R3 and R4 are H, halo, hydroxy, 1-4C alkyl or alkoxy, trifluoro methyl or cyano, one of them can also be nitro, or R3 and R4 are together 1-2C alkylenedioxy. R5 is H, alkyl, hydroxy, alkoxy, amino (opt. substd. by 1 or 2 alkyl, by one alkanoyl, or by 1 or 2 alkoxycarbonyl) all alkyl having 1-3C, or is a methylamino or ethylamino gp. substd. by trifluoromethyl. R6 is H, alkyl, phenalkyl, alkanoyl or alkoxycarbonyl, (all alkyl 1-3C) or 3-5C alkenyl. R7 is 1-3C alkyl). They are made e.g. by reacting N-H benzazepines with Z.E.N(R6)G- substd. benzenes (Z is a leaving gp.). - (I) reduce the frequency and oxygen-demand of the heart, and have a long-lasting effect with reduced side effects (esp. low antimuscarinic effect), so are useful for treating sinus tachycardia and for preventing or treating ischaemic heart disorders. The only cpd. treated has intravenous and oral LD50's in mice 89-1350 mg per kg, respectively.
